x = 4
To know if there is a perfect square you gotta see if there is a minus sign before the second coefficient and when you square the second coefficient divided by 2 you should get the third coefficient
Answer:
Rocket can hold maximum 4.5 gallons of water.
Step-by-step explanation:
Volume of the rocket = Volume of the cone on the top + Volume of the cylinder at the bottom
Volume of the cone = 
Here r = radius of the circular base
h = height of the cone
Volume = 
=
cubic inch
Volume of the cylinder = 
Here r = radius of the base
h = height of the cylinder
Volume = 
= 256π cubic inches
Volume of the rocket = 
= 
= 1038.82 cubic inches
Since 231 cubic inches volume of a rocket can hold water = 1 gallon
Therefore, 1038.82 cubic inches space can hold water
=
= 4.497
≈ 4.5 gallons
Rocket can hold 4.5 gallons of water.
Well starting with just the first statement b is congruent to c by vertical... yes. because they are formed by the intersection and non adjacent. so A and C are still okay.
answer choice B on the other hand b is congruent to h by corresponding that is not true.. one they are not corresponding and two they are supplementary because they are same side exterior angles. so you can eliminate B.
now the next line in answer choice a.. c and e are supplementary by ss interior... yes that is correct.
now the next line in answer choice c.. d and h are supplementary.. that is wrong.. d and h are corresponding and therefore are congruent so you can eliminate answer choice C.
just checking the rest.. e and h are congruent by vertical.. correct.. and finally substitution to finish the proof. So A is the correct proof.
